FAQ

Fresh air from outside is drawn into the home through the cooler located on the roof. The cooler has a water supply that wets four pads, the air is then drawn through resulting in air being cooled through the process of evaporation. As an example if you wet your finger and then blow on it you will feel the cooling effect of evaporative cooling.

This cooling system is ideal for dryer climates.

The amount of water used is in direct relation to the outdoor humidity level. If it is a hot dry day the unit will use more water through evaporation. The water usage is minimal, and you will not notice the impact of using an evaporative system during Melbourne’s summer period.

The use of electricity is very low.  It’s needed to drive a fan and a small water pump.

There is no zoning option on the evaporative cooler. However a simple method that is very effective is to control the air by slightly opening windows in the room you want the cool air. The evaporative system slightly pressurises the home therefore an open window immediately directs the air to that area.

In an ideal situation a house plan with accurate room dimensions we will need to provide an accurate quotation. In some cases this is not possible and a site visit is required to draw up a floor plan and take measurements.

It will cool your house on most days however when there is high humidity the evaporative system does not work as effectively.

A refrigerated system will provide cooling throughout extreme heat as it is not impacted by humidity levels.

This is the most effective form of cooling. The process is to transfer heat. Heat is absorbed into a refrigerant gas (what?? Chamber??) and dispersed in another area. In summer the heat in your home is collected by the refrigerant in the indoor fan coil unit and dispersed outside through the condenser unit. It works on the same basic principle as your refrigerator.

In winter a reverse cycle system heats instead of cools your home.

For refrigerated cooling system this is not recommended, however if you have an evaporative cooler installed then it is a requirement to have the windows and or doors open for operation.

Our heating and cooling specialists do an on-site visit and calculate the heat load on your home. We are then better placed to recommend the right heating and cooling system to suit your home.

A split system is a unit that can heat or cool a room/area but not the whole house. They are generally wall mounted.

Yes. Home insulation, window coverings, open doors and windows as well as the set point all affect the running costs considerably. For example, every 1 degree temperature difference should result in approximately a 6 percent increase in running costs.

Gas heating can be cheaper to run in Melbourne however Heat Pump technology and sensible zoning now means reverse cycle systems can be as cheap or cheaper to run.

Generally, yes. However, it depends on the brand and number of units. There are systems that require two controllers.

It depends on whether your house has been built on a slab or on stumps. Heaters can either be installed in the ceiling space, under the floor or external to the house with only the ducts running underneath the property.

Yes you may require additional filtration to assist in managing dust etc but generally they will be suitable.
